Inorganic oxidizer detection from propellants, pyrotechnics, and homemade explosive powders using gradient elution moving boundary electrophoresis

February 1, 2021

Author(s)

Shannon T. Krauss, Thomas Forbes, Dillon Jobes

Advancement in rapid targeted chemical analysis of homemade and improvised explosive devices is critical for the identification of explosives-based hazards and threats. Gradient elution moving boundary electrophoresis (GEMBE), a robust electrokinetic

GRADIENT ELUTION MOVING BOUNDARY ELECTROPHORESIS OF HOMEMADE FUEL-OXIDIZER EXPLOSIVES

September 21, 2020

Author(s)

Thomas Forbes, Shannon T. Krauss, Dillion Jobes

The analysis of complex samples without extensive preparation steps (e.g., filtration or centrifugation) is a persistent challenge for applications ranging from forensic identification to high-throughput security screening. Here, a capillary-based

Trace Detection and Chemical Analysis of Homemade Fuel-Oxidizer Mixture Explosives: Emerging Challenges and Perspectives

September 4, 2020

Author(s)

Thomas Forbes, Shannon T. Krauss, John Gillen

The chemical analysis of homemade explosives (HMEs) and improvised explosive devices (IEDs) remains challenging for fieldable analytical instrumentation and sensors. Complex explosive fuel-oxidizer mixtures, black and smokeless powders, flash powders, and

Detection of fuel-oxidizer explosives utilizing portable capillary electrophoresis with wipe- based sampling

June 20, 2020

Author(s)

Shannon T. Krauss, Thomas Forbes, Jeffrey A. Lawrence, John G. Gillen, Jennifer R. Verkouteren

Portable analytical instrumentation that can provide an alarm indication for the presence of explosives and related components is critical for the identification of explosives‐based hazards and threats. Many explosives incident reports involve an inorganic

Emerging techniques for the detection of pyrotechnic residues from seized postal packages containing fireworks

January 24, 2020

Author(s)

John Gillen, Thomas Forbes, Jennifer R. Verkouteren, Shannon T. Krauss, Karlijn Bezemer, Arian C. van Asten, Peter J. Shoenmakers, Mattijs Koeberg

High volume screening of parcels with the aim to trace the illegal distribution and selling of fireworks using postal services is challenging. Inspection services have limited manpower and means to perform extensive visual inspection. In this study, the

Separation and detection of trace fentanyl from complex mixtures using gradient elution moving boundary electrophoresis

September 27, 2019

Author(s)

Shannon T. Krauss, Thomas Forbes, David Ross

The current opioid epidemic remains an ongoing challenge, exacerbated by the extreme potency of synthetic opioids (e.g., fentanyl and fentanyl analogues), leading to an increase in adulterated heroin-related deaths. The increasing prevalence of fentanyl
